Do not force the hydrant in the open-ing direction beyond fully-open as indicated by sudden resistance to turning. If water does not flowwhenthehydrant isopen, it isprobablyduetoa closed valve upstream from the hydrant.Alwaysopenthehydrantcompletely,neveronlypartially.Ahydrant that is partially open will allow pressurized flowthroughthedrainvalve,whichmaywashawaythesoil from theareasurrounding thebase,or thepartially open main valve may trap small stonesor other debris between the valve seal and seat.

Note: Where grease is specified, use an AMERICAN Flow Control recommended food grade grease.

2.

If it is necessary to add lubricant, turn operating nut back from tight closed position until it turns freely,then remove pipe plug in top of operating nut andpump food grade grease into operating nut. DONOT OVER PRESSURE LUBRICANT OR OVERFILL HYDRANT WITH LUBRICANT. FAILURE TOFOLLOW THESE INSTRUCTIONS WILL RESULT INHARDOPERATIONOFTHEHYDRANT.SHOULDHARDOPERATIONOCCURREFERTO“TROUBLESHOOTINGGUIDE”DETAILEDINTHISMANUAL.Remove all nozzle caps, clean rust or corrosion fromthreadsofnozzlesandcaps,andreplacecapgaskets if necessary.

Twice per year, open the hydrant completelyandflushforseveralminutes.Openandclosevalvetomakesureitworksproperly,andcheckforleaks.Remove a cap and verify that the hydrant is draining properly. After themainvalve isclosed, thewaterin the hydrant should drain rapidly. If it does not, the drainportsmaybeclogged.Tocleardrainports,installnozzle cap, and tighten until water tight, then open hydranttwoorthreeturnsforseveralminutes.Thiswillleavedrainportpartiallyopenandpermitwaterpressuretowashouttheobstruction.Ifthismethodisunsuccessful,removetheoperatingrodassemblyandcleanthedrainmechanism.Ifneitherofabovemethods permits water to drain, it indicates thatthe drainage area around the hydrant base should be rebuilt.

AMERICAN Flow Control strongly recommends that you follow routine maintenance on fire hydrants as outlined in AWWA Manual M17 for Installation, Field Testing, and Maintenance of Fire Hydrants. The ease of operation and the frequency of repair depends on the condition of the water system and the maintenance given. Dirt, gravel and other foreign material in the hydrant may prevent it from closing or draining properly, which may result in damage to the hydrant main valve. Under most operating conditions, AMERICAN Flow Control recommends semi-annual lubrication and inspection of fire hydrants.

Problem Solution1. Operating nut turns freely but hydrant does not open.

2. Hydrantwillnotshutofforgroundaroundhydrantis highly saturated.

3. External leakage is noticed around the operating nut.

Flush hydrant in fully open position (watch to see if rocks or other foreign objects flush out of thebarrel).After flushing for several minutes, shut off thehydrant. Watch for severalminutes to see if flowstops.Placehandoveropenhosenozzle;suctionshould be felt, indicating hydrant is no longer leak-ing and drains are working properly.If flushing does not solve the problem, it wouldindicate that something is trappedor has cut themainvalverubber.Safely followtheseatremovalinstructions to replace the valve. Check threads on bronze seat to be sure that it is not damaged. Ifthreads appear worn or bent, replace the bronze seat.If replacing the valve does not stop the leakage, bolting at the hydrant shoemay be loose or thebase gasket is damaged. The hydrant must beexcavatedtomaketherepair.

It is considered safe practice to close the auxiliary valve ahead of the hydrant, or use another means to cut off flow and pressure to the hydrant.Alwaysstanding to thesideof thehydrantandaway from thedi-rection of the hydrant caps, loosen one of the hose caps to relieve anypressurethatmaybepresentinthehydrantbarrel.
